IMPROVEMENT 1N MACHINES FOR MAKlNcHoRsEsl-IOES.

Specification forming part of Letters Patent No. 84,04 3, dated Novemberl0, 1868.

To all whom it may concern:

Be it known that I, J AGOB ZEPF, of Troy, in the county of Rensselaerand State of New York, have invented a new and usefulMachine for Formingand Pressing Horseshoes; and I do hereby declare that the following is afull, clear, and exact description of the construe tion and operation ofthe same, reference being had to the annexed drawings, makin ga part ofthis specication, in which-,-

Figure lis a side elevation. Fig. 2 is a section on plan A B; Fig. 3,plan; Fig. 4, plan of a device for delivering the shoe-blank to thedies.

Upon a bed or table, C, are two raised standards, D D, near the top ofwhich is a shaft, E, upon which and between the standards D D aresecured. the cams F and G. Below the shaft E, and between the standardsD D, is a cross-piece, H, through which, in suitable bearings, play thevertical plungers I and J, which are operated respectively by the cams Fand G. To the plunger I is attached a cutter, h, for cutting the blankfrom the bar. To the plungerJ is attached the male die i, of the sizeand shape of the shoe desired to be made. Both the plungers havesuitable springs attached, for the purpose of bringing them back intoposition after being acted upon by the cams F and G. Swinging upon thecross-piece His an arm, l, to the lower end of which is attached aroller, for bearing upon the bar of iron as it is fed to the machine,for the purpose of keeping it down on the bed. At the rear of the bed Ois a shaft, K, to which are secured the cams L and M M. Moved and workedby the cams M M are two eccentrics, N N, which impart a reciprocatingmotion to the inclined planes O O, and to which they are connected bythe connections P P, which connections can be lengthened or shortened bythe screw-couplings Q Q in the bed of the machine. Between the standardsD D, and moving on suitable ways or guides, are two dieheads, S S.Attached to the outside of the dieheads are suitably-inclined planes TT, which are acted upon by the inclined planes O O. At the inside of thedie-heads are attached the halves U U of a female die, of a size andshape to correspond to the male die t'. Extending from and operated bythe cam L is a reciprocating rod, It, to the forward end of which isattached the fork or tender V, for delivering the blank to the dies. Atone end of the shaft E is a gear, W. At the other end is a bevelgear, X.At one end of the shaft K is a gear, Y, and at the other a cam, Z. Onone side of the machine is the feeding apparatus, consisting of avertical shaft, a, the bevel-gear b, and the milled feeding-wheels c andd. The feeding-wheel d turns upon a shaftin a reciprocat ing arm, c,which is operated by the cam Z. At the sides of the machine areset-screws ff, which act upon the plates g g so as to bring the inclinedplanes O O nearer the center of the machine, thus bringing the die headsnearer together. Extending from the outside of the die-heads S S, andbelow the inclined planes T T, are two rods, j j, which extend throughthe sides of the machine, and which have suitable springs attached,which serve to keep the die-heads S S apart, except when they are beingacted upon by the inclined planes O O.

The construction of the male die i is clearly shown in the section ofthe machine, Fig. 2, in which it will be seen that it has creasers 7a kattached, and that the part below the creasers is smaller, and extendsdownward between the die-heads S S, and conforms, just below thecreasers, to the center of the shoe.

The manner of operating the machine is as follows: A bar of iron, afterbeing brought to a proper heat, is placed between the feedingwheels cand d. The cam Z then moving the arm e forward causes the feeding-wheelsto bear upon the iron a sufficient time to feed it forward a suitabledistance. The cam F then operating upon the plunger I, with its cutterh, forcing it down, cuts the blank from the bar of iron; the cam l thenmoving the rod It and fork or bender Y forward, forcing the blankagainst and bending it around the male die t' under and below thecreasers k k the cam G then operating upon and forcing down the plungerJ and male die t', bringing the part of the die below the creasers 7cL', with the blank for the shoe between the halves U U of the femaledie; the cams M M then operating the eccentrics N N, and, by means ofthe connections P P, moving forward the inclined planes or cams O O,which, acting upon the inclined planes T T, move toward each other thedieheads S S, with the halves U U of the female die, causing them topress upon and form thev outside of the shoe. vThe male die at the sametime pressingdown upon the shoe-blank, pressing it between the male dieand the top of the female die, forms the top and bottom ofthe shoe, andat the same time creases it. The cams M M, by means of the eccentrics NN and connections P P, then drawing back the inclined planes() O, allowthe die-heads to operate, and the finished shoe drops down through theaperture thus formed into aproper receptacle.

What I claim as new, and desire to secure by Letters Patent, is

1. The arrangement of the sliding arm e and Witnesses:
